Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at ...

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied ...

A 2471 B.C. solar eclipse may have triggered a break from Egypt’s sun worship, influencing Pharaoh Shepsekaf’s defiance and ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

In other words, if scientists can show that Earth's core contains a lot of helium-3, it will strongly suggest that the planet formed quickly, settling a long-standing debate about the birth of the ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

By coring the seabed at 850 m water depth in Disko Bay off Greenland's west coast, researchers from the University of ...
